SAUSAGE CASING AND METHOD OI MAKING SAID.

Application fled lioveinber 10, 1826. Serial No. 147,582.

This invention relates to the manufacture" of pieced sausage casings.

The invention is predicated on my discovery that a straight sausage. casing may be 7 made up of a intestine The primary object of the invention therefore is to produce a sausage casing, known plurality of pieces of curved to the trade as a straight casing from a Inrality of pieces ofcurvedv ntestine sewed gether.

Another object is to produce an article of exceedingly low cost by utilizing the curvedintestine which has hitherto been considered as practically useless and which is sold at aprice of about one fifteenth that of the straight intestine.

A further object is to provide a straight sausage casing which is thin and free from fat and also onewhich will present a pleas- ;ing' appearance by virtue of its smooth outer surface. a

factory as it is practically impossible to free the intestine of the fatty portion without tearing the outer wall.- Hence the casing forme by such a portion of the intestine is of necessity relatively heavy and contains a great deal of fat.

- A further object inproducing a casing in the manner about to be described liesinthe fact that the time of smokin sausage housed in this casing is reduce to one fourth that requiredito smoke a sausage housedin the, heavy fattycasing now in common-use, Other objects and advantages will appear from the following description of an illustrative embodiment of the invention.

,In the drawings:

Figure 1 represents a portion of the curved intestine which is used in the manufacture of the casing.

V Fig. 2 is a perspective view showing two pieces of the casing stitched together. 1

fily'be performed. intestine is a laborious one and very unsatisree pieces joine a tube'it mayk have. been sew Fi 3 is a perspective view showing a third portion of the casing stitched to the other two'portions shown in Figure-2.

Fig. 4 is a fragmentary end view of the casing showing a method of stitchin the three pieces together to form a round end to the casing.

Fig. 5 shows the sausage casing completed, filled and tied. i

The following is a complete description of I ,a method used to form a completed straight sausage casing 10 as shown in Figure 5 of the accompanying drawings,lthe casing be ing made up of a plurality of pieces 11, 12 and 13, in this instance three, which are sewed together along their side edges.

'These pieces are formed by slittin the,

curved intestine 14 (shown in Fig. 1) ongie tudinally, preferabl alo a vein .15 which lies on the inner si e of t e convolutions of Y the intestine and then cutting the strip into desired lengths to form the pieces 11, 12 and 13. In some instances, however, it may be deemed advisable to cut the intestine into. proper lengthsbefore slitting them. These intestines 14 are received by the sausage manufacturer in barrels inan aqueoussolution and are termed salted. The 0' oration of slitting the intestines is prefers. 1y performed after they have'been blown up by means of compressed air and permitted to dry to the point where the succeeding operation of sewing the 'ieces together may read- Two ieces 11 and 12 (as shown in Fi 2) are t en sewed together along (one of t eir side edges by means of the stitching '16. A third piece 1 3 of the intestine is then sewed along oneside edge to the piece 11 by means of the stitching 17 and the remaining side edge is sewed to the free edge of piece 12 by means of the stitching 18. As shown, in :3.) After having the together in the form of be deemed expedient to close one endof t in Figure 4. The casing having been completely stitched on the reverse side is preferabl "turned insideout so that the seams left min the stitchin will be hidden and the outer surface [of ecasing will beperfectly smooth:-

The three pieces 11, 12' and 13 each having been cut from a curved intestine will have a tendenecg together. It is by virtue e tube. 'This 1s accomplished by, means of a curved seam 19 best illustrated to twist even after they of this twisting eifect and the coaction between the three pieces that a straight casing is formed. When the casing is filled (as shown in Fig. 5) the stitching 16, 17 and 18 will follow a line of approximately helical form and thus produce a substantially straight casing from the curved pieces employed. v

While an illustrative embodiment of the invention has been described with the use of three pieces to form the casing, it is understood that the same result may be accomplished by the use of two or more pieces and ence the invention is to be limited only to a plurality of pieces as defined in the appended claims.

1. A pieced sausage casing comprising a plurality of strips of curved intestines each formed b slitting the curved intestine 1ongitudinal y, and means for securing said strips together along their side edges, said of substantially straight form.

2. The method of producing pieced sausage casings from curved intestines which consists in longitudinally slitting pieces of curved intestines of appropriate lengths to open the same and securing said pieces together along their side edges to produce a sausage casing of straight form.

3. The method of producing pieced sausage casings from curved intestines which consists in taking pieces of curved intestines of appropriate lengths, slitting each piece longitudinally along the vein thereof to 0 en the same, and securing said pieces toget ier along their side edges to form a sausage casing of straight form. a

4:. The method of producing pieced sausage casings from curved intestines which consists in longitudinally slitting pieces of curved intestines of appropriate lengths to open the same, drying said pieces to permit sewing, and sewing said pieces together along their side edges to produce a sausage casing of substantially straight form. strips coacting to produce a sausage casing In witness whereof, I hereunto subscribe my name this 5th day of November, 1926.
